Well written report. That night I was pushing back and watched them taxi past. They were close enough for me to see the pitot heads but I must admit I didn’t see the red tags. I was held at C8 on B and watched the whole thing. They subsequently closed the runway and we had to use 32. Just made it weight wise using bleeds off.
Sill feel guilty for not noticing anything abnormal. We even joked “there goes disappearing Airlines”. The landing looked exciting and I am impressed with the 330 back up airspeed indicator.
